Definitions

• the invention generally relates to elemental compositions formulated for cleansing and/or antimicrobial actions on biological and inanimate surfaces. More particularly, the invention relates to combinations of halogens, such as for nonexclusive example iodine, chlorine, bromine and others, and/or oxygen and oxygen compounds, and/or metals such as for nonexclusive example gold, silver, copper, zinc and others, deliverable as [1] topical cleansing and antimicrobial additives applied to multiple anatomical locations, [2] inanimate surface cleansing antimicrobial, and as [3] surface coating on both permanent and temporary devices, and/or [4] otherwise. Further enhancements by additional additives are included such as to prevent and/or erode biofilm formation and/or functionalities, and these may be dependent on the biological organ or tissue of application or other use.
• halogens such as for nonexclusive example iodine, chlorine, bromine and others, and/or oxygen and oxygen compounds
• metals such as for nonexclusive example gold, silver, copper, zinc and others
• Surgical procedures such as transurethral resection of prostate gland, radical prostatectomy, pelvic floor reconstruction, use of artificial urinary sphincters, and others, may successfully rehabilitate bladder and urethral channel functions in some patients.
• pads, pull-ups, and diapers e.g., used mostly by females, but also by males
• indwelling urinary catheters e.g., used mostly by males, whose use may involve suprapubic (abdominal) or urethral catheters
• Urinary catheter users develop catheter associated urinary tract infections (“CAUTI”) at a rate of approximately 5% of users/day. Thus, virtually all chronic urinary catheter users have chronic CAUTI.
• CAUTI catheter associated urinary tract infections
• NASH National Institutes of Health
• CDC Center for Disease Control
• FDA Food and Drug Administration
• catheter associated urinary tract infections are particularly a problem.
• NIH, CDC, and FDA have all identified CAUTI as one of the most common and expensive infectious diseases in the United States.
• Prophylactic use of antibiotics to treat these infections has been discouraged, because of evolution of antibiotic-resistant microbes.
• Microbial colonization risks of indwelling catheters therefore, remain an unsolved clinical problem in a growing, aged population. The infection risks are similar regardless of whether the catheter is placed abdominally or transurethrally.
• CAUTI causes of CAUTI include microbial attachment of skin microbes to external surfaces of indwelling catheters, followed by explosive growth and concurrent biofilm formation. Microbes commonly adhere to cellular and inanimate surfaces and then create and enshroud themselves within a protective biofilm. Daily migration of colony-rich biofilms, principally on catheter external surfaces toward the bladder lumen, induces colonization of bladder urine. Colonized bladder urine occurs at a rate of approximately 5% of catheter users per day. Thus, virtually 100% of chronic-use catheters have colonization after ⁇ 20+ days of indwelling catheter use. Consequently, long-term catheter users typically have colonized urine for as long as the catheter is indwelling.
• urine is the excretory pathway for muscle (i.e., proteinaceous) and bone (i.e., calcium and phosphorus) waste resulting in high urinary concentrations of urea and high concentrations of calcium and phosphorus dissolved in urine.
• Some bacterial species e.g., all Proteus species and some strains of Klebsiella and Pseudomonas ) make urease, an enzyme that interacts with urea to robustly and quickly alkalinize urine.
• Alkaline urine triggers precipitation of calcium-phosphate crystals which over a few days attach and grow onto catheter surfaces as encrustations and/or as bladder stones.
• Quorum signaling is a process in which bacteria communicate with each other by secreting and sensing diffusible signaling molecules called “autoinducers.” When these signaling molecules exceed a threshold concentration level, they auto-stimulate genes that enable bacteria to behave as a multicellular population, to benefit their survival.
• Staphylococci bacteria create autoinducers that upregulate the expression of multiple toxins and enhance the formation of biofilms. These phenotypes are the hallmark of staph pathogenesis and are a cause of resistant and persistent infections and even death.
• Acetohydroxamic acid is an FDA certified, water-soluble, oral, therapeutic agent that is excreted in urine where it blocks urinary microbe generated urease thereby allowing urine to maintain its physiologic acidic pH.
• Witch hazel is a botanical native to the Northeast USA, among other locations, which includes hamamelitannin, gallic acid, and perhaps other agents that effect quorum signaling inhibition induced by Staphylococcal and multiple other microbial species and strains.
• Metals such as for example, gold, silver, copper, zinc, and others, are naturally microbiocidal as are halogens (chlorine, bromine, iodine, etc.) and oxygen. Metals and halogens may be less susceptible to microbial mutations and emergence of resistance microbial species than are the man-made synthetic antibiotics.
• Embodiments of the invention include elemental compositions formulated for cleansing and/or antimicrobial actions on biological and inanimate surfaces.
• Non-exclusive embodiments include combinations of halogens, such as iodine, chlorine, and bromine and metals such as gold, silver, copper and zinc and/or oxygen and oxygen compounds, deliverable as topical cleansing and antimicrobial additives applied to multiple anatomical surface locations, and inanimate surfaces as both cleansing and antimicrobial, surface coatings on both permanent and temporary devices and/or other uses.
• Non-exclusive additives in embodiments include acetohydroxamic acid (AHA) and/or witch hazel concentrate.
• AHA acetohydroxamic acid
• AHA blocks microbial urease-induced alkalinization and thereby supports urinary acidification thereby reducing risk of calcium-phosphate crystallization and stone formation.
• AHA maintains physiological acidification of urine and thereby potentiates further added acidification that enhances the functionality of elemental agents, such as iodine and oxygen.
• Witch hazel concentrate can block new biofilm formation and erode existing biofilm formation induced by several types of urinary pathogens.
• Witch hazel concentrate is functional as a dissolved urinary additive and as allopathic surface coating.
• Other additives are possible, such as for non-exclusive example, metals like gold, silver, copper, zinc, and others, and/or other additives.
• An embodiment of the invention is an antimicrobial bladder additive liquid composition including iodine and hydrogen peroxide.
• Another embodiment of the invention is acidification of the iodine/hydrogen peroxide mixture to a pH of approximately 1.8-2.8
• Another embodiment of the invention is a method of antimicrobial action that includes providing an aqueous molecular [non-ionic, non-polymerized] I 2 iodine, and providing an aqueous hydrogen peroxide to the aqueous iodine for a first composition, and acidifying the first composition.
• Another embodiment of the invention includes addition of witch hazel concentrate or its most active botanical ingredients, consisting of hamamelitannin and/or gallic acids. These agents prevent and erode microbe induced biofilm formation on prosthetic and cellular surfaces thereby exposing adherent microbes to the killing effect of iodine and hydrogen peroxide.
• Yet another embodiment of the invention includes addition of acetohydroxamic acid [AHA].
• AHA serves as a bladder additive formulation to prevent microbe induced alkalinity of urine that serves to negate the acidic aqueous bladder additive.
• Yet another embodiment of the invention includes additions, substitutions, or omissions to an acidic iodine and hydrogen peroxide combination particularly targeted for use in or for a particular anatomical organ or a particular tissue coating.
• Embodiments include iodine solution and hydrogen peroxide, as well as other formulations.
• embodiments also can include acidifying agents, such as acetohydroxamic acid (AHA), and/or organic extracts, such as Witch hazel extracts (WH), comprising hamamelitannin and/or gallic acid, combined with the iodine and hydrogen peroxide.
• AHA acetohydroxamic acid
• WH Witch hazel extracts
• the novel combination has been determined to be effective as an antimicrobial, for topical applications, including to surfaces of urinary catheters and devices, and as a topical rinse of the bladder lumenal mucosa, skin and other organs.
• the formulations may take a variety of forms, including liquids, rinse, sprays, ointments, creams, colloids, and others.
• Hydrogen peroxide is a compound with the formula H 2 O 2 . It is a liquid that is slightly more viscous than water. Hydrogen peroxide has been used as an oxidizer, bleaching agent and topical antiseptic. As a topical antiseptic, hydrogen peroxide has been used as a topical “wipe” on inanimate work surfaces and topically on skin and selected organs (i.e., eyes, ears, etc.) in humans and other animals. Hydrogen peroxides with pH of about 4.0 are generally available over the counter as 3% topical cleansing agent for human skin.
• Hydrogen peroxide has not been used systemically for internal organs as antimicrobial. It has been determined that antimicrobial effectiveness of hydrogen peroxide is very dependent on pH, as is steady blood pH of about 7.0. Hydrogen peroxide has not previously been used as a bladder additive, though hydrogen peroxide has been discovered to be naturally present bladder urine having been produced by bladder mucosa; thus, H 2 O 2 is present in physiological urine in small concentrations.
• Dilute concentrations of hydrogen peroxide [2-3%] that are acidic are potent antimicrobial agents, such as, for example, in bladder and urine applications.
• a solution of 3% hydrogen peroxide is combined with an acid, for non-exclusive example, acetylsalicylic acid (ASA), i.e., aspirin, or hydrochloric acid, or acetic acid or or other acid.
• ASA acetylsalicylic acid
• Desired acidification is to a pH of about 1.5 to about 2.5.
• the acidified solution has been found to be an effective and potent antimicrobial, which may be employed topically or introduced internally [into specific organs, spaces, or cavities] of humans and animals, such as for bladder rinse and as topical application to skin and/or catheter or other permanent or temporary device surfaces.
• Aqueous iodine in about 3% and 6% solutions [as tincture of iodine, i.e. dissolved first in ethanol and then in water] or as Lugol solution [i.e. a mixture of I 2 and potassium ionized iodine] are commercially available as a topical skin cleansing agents. Both formulations are used to clean and disinfect inanimate and cellular surfaces. Only the I 2 moiety is antibacterial. The I 2 moiety can be increased by solubilizing the iodine in ethanol and/or by acidifying the aqueous mixture.
• the solution is often found in mouthwash or topical wound treatment for small wounds, and similar product form.
• the solution typically has pH of about 4.5.
• Aqueous iodine has not generally been used as a topical bladder rinse or for other topical internal bodily use. It has been found that the molecular iodine component (I 2 ) of the aqueous solution is the only antimicrobial component.
• the percent of molecular iodine in the aqueous solution can be increased by adding iodine to ethanol and by mixing the ethanol solubilized I 2 with water and by increasing acidity of the aqueous solution, for example by lowering the mixture to pH of about 1.5 to about 2.0.
• Aspirin, hydrochloric acid, acetic acid, benzoic or other acids may lower to this pH. At such acidic pH, the acidic aqueous solution has been found to be a tolerable antimicrobial solution for introduction into the bladder, as well as for topical application to skin, and other cellular or inanimate device surfaces.
• Organism Staphylococcus aureus
• Witch hazel ( Hamamelis ) is a genus of flowering plants in the family Hamamelidaceae. Four species are found in North America ( H. ovalis, H. virginiana and H. vernalis ), and one species each is found in Japan ( H. japonica ) and China ( H. mollis ). The leaves and bark of the North American witch hazel, Hamamelis virginiana , may be used to produce an astringent decoction. This witch hazel decoction can be an extract in liquid form. This concentrated extract liquid has been FDA approved, for example, for topical application to the nose, anus and skin.
• Witch hazel liquid extract/concentrate can include such components as calcium oxalate, gallotannins, and safrole, and chemicals found in the essential oil (carvacrol, eugenol).
• Witch hazel for use as a topical can be a liquid, semisolid ointment, cream, gel or salve, as examples.
• Witch hazel extracts and concentrates are widely sold by pharmacies, grocery stores, and others, and they serve many uses to ease discomfort and provide soothing sensations.
• a particular witch hazel extract (WH) in the embodiments, determined to provide beneficial attributes, is marketed over the counter as a product named whISOBAXTM available from Staph-Off Biotech, Inc. at staphoff.com, as example.
• the whISOBAXTM product comprises about 12.66 mg of gallic acid equivalent/ml.
• the planktonic minimum bactericidal concentration/minimum inhibitory concentration (MBC/MIC) for whISOBAXTM is about 0.31/0.15 mg/ml gallic acid equivalence method (GAE) and the minimum inhibitory concentration (MIC) for biofilm trapped bacteria is about 0.47 mg/ml GAE [ ⁇ 3 ⁇ higher than the planktonic level].
• the hamamelitannin molecule is substantially as follows:
• Hamamelitannin acts as a quorum signaling inhibitor (QSI) that suppresses microbial biofilm formation and toxin production of bacteria.
• QSI quorum signaling inhibitor
• witch hazel Other anti-microbial active components of witch hazel include gallic acid and other phenolic compounds. Gallic acid, for example, may prevent bacterial growth by binding/disrupting cell membranes.
• the various components of witch hazel extract are effective in multiple gram negative and positive bacteria that commonly colonize indwelling urinary catheters and the like.
• the primary function of witch hazel extract where deposited and in antimicrobial actions is to block microbial attachment to devices or biological surfaces, block biofilm formation, erode existing biofilm and block microbial toxins from being produced, and lower the MIC of other anti-microbial agents.
• Acetohydroxamic acid is a urease enzyme (protein) inhibitor. Proteus and certain other urinary microbes make urease which alkalinize urine by splitting abundant urinary urea. Alkalinity decreases microbiocidal functionality of iodine and hydrogen peroxide as antimicrobials. Addition of AHA to combinations of aqueous iodine and/or aqueous hydrogen peroxide are found to block urease induced alkalinity and thereby improve the microbiocidal efficacy of Iodine and/or hydrogen peroxide as antimicrobials, particularly in presence of Proteus, Klebsiella and Pseudomonas and other microbial species that make and secrete urease.
• AHA urease enzyme
• combinations of AHA with acidic aqueous iodine and hydrogen peroxide are found to be particularly effective antimicrobial compositions.
• Aspirin i.e., acetylsalicylic acid
• acetic acid acetic acid
• benzoic acid acetic acid
• hydrochloric acid or other acidic and tolerable agents
• added to the combination either to iodine or hydrogen peroxide, alone or together, decreases the pH of the solution.
• the lowered pH increases the concentration and microbiocidal effectiveness of molecular iodine [and decreases the ionic concentration of iodine].
• the acidic aqueous solution is more efficacious than individual components in limiting microbial growth. Testing of the combination of aqueous ingredients reveals that no reactants, such as precipitates, flocculates, or color change (other than dilution), results.
• increasing the concentration and acidity of either or both iodine and hydrogen peroxide, while simultaneously minimizing microbe protective biofilm formation with WH furthers antimicrobial efficacy of the iodine and hydrogen peroxide.
• the WH prevents and erodes microbe induced biofilm on cellular and prosthetic surfaces. Exceptional bench-top testing results have been obtained in antimicrobial action from the iodine, hydrogen peroxide and WH combination in the testing of multiple Proteus species.
• addition of AHA to the combination of either iodine, hydrogen peroxide, and/or WH, or combinations thereof, is effective to block microbe induced alkalinization of urine thereby enhancing potency of iodine and hydrogen peroxide as antimicrobials.
• Microbe induced alkalization e.g., of urine
• Urine is sensitive to alkalinity because microbial urease reacts with dense concentrations of urea dissolved in urine. Urea in high blood concentrations is a toxin that can cause illness and even death.
• the addition of AHA into urine to limit the microbe induced alkalization is therefore beneficial and in combination with other agents yields unexpectedly favorable results in the combination.
• Silver ions as well as other metals, for nonexclusive example, copper, tin, zinc, lead and others, can also have biocidal effects.
• various halogens such as, for nonexclusive example, iodine, bromine, chlorine and others, may contribute to antibacterial action.
• the mechanism of action of metals and halogens is believed to involve penetration into bacterial cells, turning deoxyribonucleic acid (DNA) molecules into a condensed form and thereby hindering cell replication.
• Silver colloid for example, has been approved by FDA for topical and oral use. Silver colloids can be a preferred drinking water sterilant when used in 20-100 mcg/liter concentrations. Russian space craft employ silver colloids to recycle urine and other body fluids. Other metals and colloids of metals are therefore effective for sterilization as well as other antimicrobial effects.
• a particular witch hazel extract, whISOBAXTM has about the following characteristics:
• whISOBAXTM was combined with silver ion colloid.
• a particular silver ion colloid in tests, determined to provide beneficial attributes, is marketed over the counter as a product named Ultra SilverTM available from UltraSilver.com or Amazon.com, as example. Both whISOBAXTM and Ultra SilverTM are FDA certified as dietary supplements.

• silver and other metals and halogens can be included to further enhance the combination of agents effectiveness as an antimicrobial.
• Iodine and hydrogen peroxide combination kills microbes at greater dilutions (i.e., lower concentrations) that does either agent alone. Neither of these agents has previously been studied as a bladder additive or device coating, or similar internal or device application. Potency of both iodine and hydrogen peroxide are increased in an acidic liquid formulation and are reduced in an alkaline liquid formulation. Studies reveal no interactivity or reactivity of the two agent combination, at room or body temperatures.
• WH concentrate and its components hamamelitannin and gallic acid, have been observed to effectively block and erode cellular surface and inanimate surface adherent microbes.
• the combination of WH (or components of it) with iodine and hydrogen peroxide prevent and strip away microbe enshrouded biofilm thereby exposing adherent microbes to the efficacious and enhanced antimicrobial effects (e.g., microbe killing effects) of iodine and hydrogen peroxide.
• the combination has been observed to exceed antimicrobial effects experienced with the individual components.
• acetohydroxamic acid included in the combinations further blocks microbe induced alkalinization of urine. This increases the effectiveness of iodine and hydrogen peroxide, alone or in combination in a urinary application.
